The Samsung Galaxy S2 has many "hidden" features, which has made it one of the most popular Android smartphones on the market.
However, the Galaxy S2 does have many lesser-known features, such as the content manager, Kies Air, and its motion interaction mechanisms, screen capture and USB host.
Standard specifications on the Galaxy S2 include a 1.2GHz dual-core ARM Cortex A9 Exynos processor and 4.3-inch Super AMOLED Plus screen for the AT&T and Sprint versions, while the T-Mobile version has a 1.5GHz dual-core Qualcomm Snapdragon S3 processor, 4.52-inch Super AMOLED Plus display and a HSPA+ 42 network.
All three versions share an 8 megapixel primary camera at 1080p, NFC support and the Android 2.3.4 Gingerbread operating system.
More “hidden” specifications make the Galaxy S2 a unique smartphone on the market, such as Kies Air. It allows users to remotely manage phone content with any web browser. Users can also organize their photos, music, video and contacts, and send text messages through a computer.
Motion Interaction allows users to prompt phone commands through various motions. The motions include turn over, tilt, panning, and double tap–to control. Users can activate these features by going to Applications > Settings > Motion.
Screen Capture allows users to capture an image of their current screen. To use screen capture, users can touch and hold the Home key and Power key at the same time.
The USB host allows users to attach USB devices to the Galaxy S2, including keyboards, mice and thumb drives, with the optional USB adapter.
Samsung lists these features, actions, and a number of other tips or tricks on their website to help all users optimize the Galaxy S2.
